UNITED STATES PATENT OFFICE I PETER HUBER, OF ZURICH, SWITZERLANDAPPARATUS FOR DISPENSING OILS AND FATS Application filed December 16,1930. Serial No. 502,692.

the so-called filling stations.

The main object of the invention is to provide improved means by which apredetermined quantity of the oil may be delivered directly into thegear boxes, oil containers etc. of. motor cars by means of a hose orother flexible conduit.

A further object consists in the provision of means to prevent theleaking and spilling of oil and the automatic and accurate operation ofthe dispensing valve.

I attain these and other objects as will appear in the annexeddescription by the device illustrated in the accompanying drawings,

the invention consistingin certain novel fea-.

tures which will be hereinafter fully described and mo're particularlypointed out in the appended claims.

In the drawings Fig. -1 is an elevation, partly in section of thedispensing device. i

Fig. 2 is a top view of the same. Figs. 3 and 4 are detail views partlyin plan and partly in section of the valve arrange- Inent.

" Figs. 5 and 6 are respectively a vertical section and an elevation ofthe device to control the dispensed oil. I

Fig. 7 is a section through the automatic dispensing valve.

Figs8 and 9 show details.

The apparatus comprises a carriage 1 on which two tanks 2, 3 are mountedfor storing the oil 4 to be dispensed. The tanks 2, 3 are tightly closedandc'ommunicate by pipes 5, 6

- with a container (not shown) supplying air or gas under pressure tosaid tanks above the level of the oil 4. From tanks 2, 3 pipes 7, 8 leadrespectively to valves 9,10. Said valves are connected with a measuringvessel 13 by means of short tubes 11, 12; In said vessel 13 a tightlyfitting piston 14 is arranged. The piston rod 15 passes through astufling box in the lid of said-vessel 13 and projects into a tubularsupport 16 fixed on the lid ofsaid vessel 13. Said member 16 is providedwith an abutment to arrest the piston in its upward stroke and to varythe stroke at will to dispense predetermined quantities of oil.

The said abutment is a sleeve 35 rotatably mounted in the support 16 bymeans of a stud 33 and a cap 36 rotatably mounted on the support. Knobsfixed to said cap facilitate the turning of the sleeve 35. The latter isprovided with slots 37, 37 37" running in axial direction. The slots 3737 37 have different length. The piston rod 15 is provided with a crosspiece 38 projecting into a slot 59 of the support 16 and through one ofthe slots 37, 37 37 In the lowermost position of the piston 14 the crosspiece 38 is out of engagement with the sleeve 35 and the latter may beturned within the support to allow the cross piece to enter any of theslots 37 37 37 An index running along the slot 59 indicates the positionat which the piece 38 is arrested and denoting the quantity of oil whichis being dispensed.

To the valves 9, 10 hose members 17 17' are respectively attached and atthe free end of each hose a valve 18 is fixed adapted to deliver the oilfor instance into the gear box of a motor car. 1

The space above the piston 14 communio the bore 52 in the plug 53 of thevalve 9 with an air outlet 54 arranged inthe casin of valve 9. Thepressure acting on the 011 in the task 2 presses the piston 14 upwardsuntil the cross piece 35 strikes against the bottom of a slot 37.escapes through the pipe 32, plug 53 and bore 54 into atmosphere. Theplug of valve 9 is now turned to bring the hose 17 in communication withthe measuring vessel 13 and the space above piston 14 with thecompressed 100 In the position 85 The air above the piston 14 airsupplypipe 5. The air pressure on piston 14 forces the oil to valve 18.

The valve 18 comprises within a casing attached to the hose 17, avalvebody 19, and a valve mat 20. The seat 20 and the outflow orifice ofvalve 18 are in a common plane. The stem of the valve body 19 isprovided with a disk 24. Between the disk 24 and a-cap 40 of the casinga coiled spring 25 is arranged which tends to keep the valve closed. Inthe upper portion of the stem a cross bore 26 is provided in which twoballs 27 and a short spring 28 are arranged. The spring 28 presses theballs into annular grooves 30 or 31 according to the position of thevalve body 19. On the stem 19 between the disk 24 and a shoulder 41 apiston 22 is slidably mounted. A coiled spring 21 abutting on the cappresses on said piston 22.

If the pressure in the hose 17 attains a certain measure the piston 22is moved upward-.

ly against the action of the spring 21. The

iston 22 strikes against disk 24 and lifts to a limited extent in thepiston and provided with a stop to limit closing movement independentlyof the piston, and also with a stop engage'able by the piston when thelatter moves to closing position, a spring active to move the pistonnormally to closing position, a sprin g active to move the valve toclosing position when the piston so moves and yieldable meanscountervailed by said springs to prevent causal movement of the valvewhen the latter is in either open or closed position.

2. A supply valve as claimed in claim 1, including manually operablemeans to move the valve to closed position.

3. A supply valve as claimed in claim 1, in which the piston has achamber in which the springs for moving the piston and the valve arearranged, and in which said springs are coiled springs.

In testimony whereof I afiix my signature. 3

the same and therewith the valve body 19 i against the action of spring25. The valve body 19 assumes now the position shown in Fig. 7, theballs 27 have entered the upper groove 30, and hold the valve bodyin itsopen position. The oil is delivered. As soon as the pressure in the hose17 diminishes the spring 21 expands again and the piston 22 slides downon the stem of the valve body and strikes against the shoulder 41. The

. valve spring 25 presses on the valve body 19, the combined pressure ofboth springs 21, 25 being sufiicient to move the valve body down .on toits seat 20. The balls 27 are first forced into the cross bore 26 and.are projected into the groove 31 again as soon as the body rests on itsseat 20. The piston 22 comes to rest on the shoulder 43, the valve body19 may be pressed on to its seat by a screw 45arranged in the cap 40 andprovided with handles 44. The screw 45 may be screwed on to-the top faceof the valve body stem to keep it pressed on the seat 20.

If the pressure in the hose 17 raises temporarily, if for instance thehose 17 is sharply bent etc. the piston 22 is first moved upwardlywithout the valve body 19 being raised from the seat. Leakage andspilling of oil is thus prevented. v

The delivery of oil from the tank 3 occurs in an analogous manner andneed not be de scribed.

What I wish to claim and secure by the U. S. Letters Patent, is

' 1. A supply valve comprising a cylindrical body having a dischargespout and also having an inlet duct for fluid under pressure, acylindrical piston in the body movable toward the spout and movable inthe reverse direction by pressure of the fluid in the valve body, avalve arranged to open and close the spout and extending through andmovable
